r "Thisinvention relates toiinprovements in cigarette machine cutoffs,particularly to-the type inwhich the cutoff blade is moved in an orbitalpath intercepting the path of the cigarette rod and at the same timefollowing therod. v p

' The main object of the present invention is to provide a cutoffmechanism in which the cutoff blade and the ledger plate are carried bythe sameframe for movement in unison,

thus avoiding thelnecessityfor separate reciprocation of the ledgerplate as has hitherto commonly been the practice; In this man 7 ner, theledger plate is given the same '16 smoothicircular motion thatthefknife' receives, thus veliminating'one sourceof vibration: Moreoverthe extra parts for reciproeating the ledger plate are dispensed with.

Also when the ledger plate is separately l reciprocated, while the knifeispmovediinan orbital path, there is a-small but objectionablelongitudinal differential movement bea tween the ledger plate. andtheblade which varies the clearance between" the ledger plate 2 andknife and resultsin imperfectcuts Another object of theinvention is toprovide simple and efi'ectivemeans for rotating the blade as it travelsalong its orbital-path. Still another object of the invention is toprovide a three point connection between the I V b n Fig, 1, the cutoffs dr ven from the main I frame carrying the blade and ledger plate andthe means supporting the 'frame for movement, in order to resist thetendency of p the frame to sidesway about two points as an axis and to.resist the torque resulting from driving the blade. 1 i j b With theseand otherobjects not specifi cally mentioned in View, the invention con-L v p e p v ported 'by a' housing '22 andhousing cover 23 'inibearings24 held by aj sleeve 25 on V sists of certain constructionsandcomb'inations which will. be hereinafter fullydescribed and thenspecifically set forth in the claimshereunto appended. 7*

In the best constructions said mansincludes crankssupportingtheframe; I Preferably the frame supports :th'efblade'andledger plate respectively on uopposite sides of the: rod. The bestconstructions: further include mechanism for the; invention isbut one ofmany possiblec'oncrete emjbodimentsof thesame. gTheginvention thereforeis not to be restricted to 1 the precise details of anddescribed.

the structure shown Referring nowio the drawings asshown drive shaft 10@of (the cigarette; machine through gears 11 and-12 thelatter on thevertical drive shaft 13 which is'supported bybearings 14 and 15in asleeve 16. On the=- 1 upper end-of the shaft 13 is mounted a gear '19,Whiclrthr'ougha bevel gear 20 drives the horizontal crankshaft" 21.;Thelatter i s-supshaft- 21.. I I g I Flying supports for the knifecarrying 7 frame are provided consisting of crank pins '32}, 33 and34 oncrankshafts 21 and '27, the latter two shaftsbeing journaled-in bearings28 and 29 held in by sleeves 30 i "and 31,respectively. Crank pins 32;33and 34 by ineans'ofbearings 35, 36am f.

I wjlrespec tively," support the frame; =38 for fly- '--50 2 in-sectionof the cutoff blade shown in: Fig, ting movenien't in a"; circularorbital path.

The frame 38 together with the cover 39 forms a housing'in which thebearings of crank pins 32 and 33 are mounted while in i a verticalextension of the frame 38 there mounted a spiral gear 44 driven from avspiral gear 45 fixedly mounted on the crank pin 32. The spiralgear 44 isintegral with asleeve 46 supported by bearings 47 and carrying an arm L8mounting the wafer cutoff blade 49. A cover 50- serves as. an oilcatcher-to keep oil off the cigarette rod shafts 21', 26'a11d 27' havecounterbalanees 51 to, balance the weight 'of the revolving frame 38'. I

A grinding wheel 52' is held by. a bracket 53 which is mounted on anadjustable rod 54 held by alug 5'5 slidable in a bracket .56mountedontop of the housing- 22. Ad-

justment of the lug 55 -is accomplished by means of the'handwheel 57,the rod 58which is held by a bracket 56, which ro'd has its threaded endenteringinto lug '55.. The grinding wheel=52 is protected: by a cover 59hinged ona stud 60, while a cover 61 hinged on stud62 protects theknife49. A

burr dressing wheel 63- is held by a fork- '64 ona rod 65, adjustablymounted in a bracket G'dattached to housing 67 which forms an extensionof housing 22. A slot both-supported by saidframe, and means formovingsaid'frame in an orbital path 68 in thecover' 61 permitsthe latter to beopened without interfering with the rod 65. Stationary guide tubes 69and 70 for the cigarette rod 0 are held byhousing 67. These guides arecut away at an angle on their undersides to provide afair way for theledger plate tothe' rod. An advantage of the above construction is thatshorts drop 'out there' instead of being delivered to the collectingmechanism.
